The Obama-Warren embrace

6/26/12 5:15 AM EDT

Both candidates have had a rough month or so, but last night in Boston, President Obama and Elizabeth Warren had each others' backs. And both delivered a message that spoke directly to the Democratic base in one of the country's most liberal states.

“No, Mitt, corporations are not people,” she exclaimed. “People have hearts, they have kids, they get jobs, they get sick,… they live and they die. Learn the difference.

“And Mitt, learn this: we don’t run this country for corporations, we run it for people,” Warren continued, drawing cheers from the crowd at Boston Symphony Hall.

Warren, who is in a tight race with Sen. Scott Brown (R- Mass.), made the remarks during her introduction of President Obama.

“We face a real choice in this country, this election will be about whose side you stand on,” she said. “Over the past couple of years, I’ve seen up close whose side president Obama stands on.”

And via the White House transcript, here's what Obama had to say about his party's Senate nominee:

I just want to thank Elizabeth for that introduction, and let you know how lucky all of you are to have a chance to vote for her in the next election. (Applause.) Nobody fought harder for Wall Street reform -- the reform that is now law and protecting consumers all across the country -- than Elizabeth, reform that will end taxpayer bailouts, make sure folks aren’t being taken advantage of by mortgage lenders and credit card companies. She has been a fierce advocate since before I knew her for the middle class. She has been advocating on core issues that matter to families her entire career. She is going to be an outstanding senator from Massachusetts, and everybody here has got to turn out for her. (Applause.)

Democrats have been ambivalent, this year and historically, about how far to lean into a Wall Street-whacking message. Last night, at least, it served both candidates' interests to go there, and the trend in 2012 has been for Obama's message to trend in the direction of Warren's, rather than the other way around. It's probably a safe bet that Obama's comments will eventually appear in an Elizabeth Warren ad near you.
